Hi,

Just a beginner question about GeoMason: when I want to use check points, I
got the following:

java.io.NotSerializableException:
com.vividsolutions.jts.index.quadtree.Quadtree
       - field (class "sim.field.geo.GeomVectorField", name: "spatialIndex",

Is there a way to solve the problem?

Thanks

The version of JTS you're using is not serializable.  I understand a later version should be?

Cheers,
